9V AC Adapter for Casio Keyboards

This adapter supplies 9 volts DC at 1.5 amps to a wide range of Casio portable keyboards. It accepts 100 to 240 volts AC input, making it suitable for use in many regions. A six-foot cable provides flexible placement near a mains socket. The unit is brand new and ready for immediate use.

Who This Suits and Who It Does Not

Owners of compatible Casio CT, CTK and WK series models listed in the specifications can use this as a direct replacement power supply. It is not intended for keyboards that require a different voltage, a higher current rating, or a barrel connector other than the 5.5 mm sizes provided. Buyers needing a battery-powered or USB-C power solution should look elsewhere.

Connector Polarity and Sizes

The plug is centre-tip negative and ships with two interchangeable barrel tips measuring 5.5 mm by 2.5 mm and 5.5 mm by 1.7 mm. Matching the correct tip and polarity to the keyboard's DC input jack is the single specification that decides whether this adapter will work.
